Moses and Aaron did so . . . just as the Lord commanded them. (7:6)
The emphatic “NOW” (6:1) marks a great turning point: before it Moses failed all along the line; after it, he was on the victory side. Before this point, he got nowhere with Pharaoh; after it, he had complete authority in Pharaoh’s presence. How does the man of God become the man with God’s authority? He was still the same Moses—the same human clay. (This is why his genealogy is reported in 6:14-26 and his age in 7:7.)
The change was not in Moses. Nor was it in the freshly revealed truth about the Lord (6:2-8). The only new word in this repeated revelation of God’s character (compare 3:6ff.) is the Lord’s promise to redeem (v. 6), by which he is pledging to take all Israel’s troubles and needs as though they were his own. There is nothing new about Moses’ commission or his sense of inadequacy (6:10-12), or about the Lord’s provision to meet it (6:28-7:2). The vital clue is given so quietly we could easily miss it.
Exodus 7:6 shows us the secret: “Moses and Aaron did so; they did just as the Lord commanded them.” That’s it! Do nothing without a divine command; say what you are told to say. Tie yourself to the word of God.
Lord, teach us to hold fast and hold forth the Word of Life.
